This is a note to let you know that I've just added the patch titled ASoC: SOF: Add topology filename override based on dmi data match to the 5.8-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: asoc-sof-add-topology-filename-override-based-on-dmi.patch and it can be found in the queue-5.8 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c36a24ba16b56899f80e9be1bbbd0649074da394 Author: Sathyanarayana Nujella <sathyanarayana.nujella@xxxxxxxxx> Date: Fri Aug 21 14:56:00 2020 -0500 ASoC: SOF: Add topology filename override based on dmi data match [ Upstream commit 5253a73d567dcd75e62834ff5f502ea9470e5722 ] Add topology filename override based on system DMI data matching, typically to account for a different hardware layout. In ACPI based systems, the tplg_filename is pre-defined in an ACPI machine table. When a DMI quirk is detected, the sof_pdata->tplg_filename is not set with the hard-coded ACPI value, and instead is set with the DMI-specific filename.
